How much am I saving?

1. Didn't see the movie. sorry.

2. I would use the Penzoil since you already have it. I hve yet to see even the worst oil kill an engine that quick.

I'd reccomend if you decide to watch it, be a little under the influence of alcohol or with a bunch of people. It makes it even better..

oh... i use Mobil 1... if anyone cares for somthing on topic.

Hey, there is this new either quaker state or mobile synthetic oil. Its called "advance" and they say it can go to like 8500 - 15,000 depending on which one you buy.

Anyone ever seen that stuff and how much it costs?

Would you really trust somthing like that?... I'll stick with my 2,500-3,000 mile changes thank you. Atleast i can rest easy knowing its clean oil.

Oh no, I was just wondering if anyone has ever seen it. It has to be expensive if you can go 15,000 miles

I go by the color of the oil when I check it, once it gets dark but still brown/caramel looking, it's time. The Lucas must help 'cause it's close to time to change and I've went about 6 months/6,000 miles, of course a slight main seal leak means I have to add almost a quart over two months so that keeps it fresh.

[RedCavalierRacer]

oil leaks suck. I had one in my 96 cavalier LS because i liked to screw atound in it and I think I cracked the oil pan.

I used 10-30 Castrol GTX in my Suburban for the first 250,000 niles, changing every 3 months or 4,000 miles.

Then I switched to Castrol Syntec, changing at 7,000 mile intervals. Should have gone synthetic years sooner.

At 300,000 my oil pressure started to drop so I started substituting Lucas oil supplement for 1 quart. Wow, like new oil pressure, this stuff is STP on steroids.

At 370,000 miles I popped an intake manfold gasket, losing vacuum and drivability. Rather than change it, I decided it was time for a new engine; 4-bolt main stroker 383, World heads, Edelbrock TBI manifold and TiTec headers, etc. About 50% more hp and torque. Essentially big-block power in a small block package.

I'm breaking it in on 10-30 conventional oil for the first 5,000 miles. Considering 0-30 Amsoil. Pro racers and builders I've talked to know about it and some are testing it. I've had guys tell me their duallies have gone from 10mpg to 14 just changeing to this oil. Any non-Amsoil dealers out there with good or bad experiences to share?

[Classicrocjunkie]

You should have started to use synthetic like around 10-15,000 miles. With those high of miles, its not that good of an idea. Granted i switched mine over at 50K, but i haven't had any problems thus far at 57K.

I work at a wal-mart tire and lube express and our major brand of oil is penzoil and ive seen cars come in that have had a major amount of sludge inside the fill tube and around the cap.... From what ive seen i would not recomend penzoil to anyone... also the guy about the new synthetic its just a new formula from mobil and its mobil 5000 and then they have their extended performance that is supposed to protect for 15,000.. but i would never trust a oil for that long... As for my personal choice its valvoline for me right now im runnin maxlife 10-30.....

Question. Is it worth switching over to a complete synthetic from a synthetic blend? Or just stick to what I have because it's what I've been using?

I just got an oil change about a month ago, whent eh miles were at 21.3k I'm coming up on 24k here soon. Was thinking about switching to Mobil1 full synthetic, but didnt know if it would really help or benefit?

I've noticed though that my car has gone from 332 miles on a full tank of gas down to 240. But before I was driving ~80 miles a day, on the freeway. Now I'm not anymore. Could I really be losing that many miles off a tank of gas just from not being on the freeway the majority of the time?

Well it's time for my oil change, I think this time I'm going with AMSOIL, here's why...

Here's a link to a AMSOIL vs. Mobil1 page.

There's a guy who went over 400,000 mi on a Mack truck using AMSOIL, the engine was torn down and inspected and they found no excesive wear compared to a petro based oil with regular changes. It said the engine could be put right back in...

It may cost more, but if you can go 3 or 4 times longer than conventional oil, it's actually cheaper. Anyway, that's my post for the day.

[big dude1]

i use castrol gtx 5w-30, it works great for me, and as for that 15k stuff, i would never EVER go that long without changing my oil!

This guy came into my work the other day to get a oil change and he brought his own oil and it was called royal purple.. Does anyone know anything about this?
